CRI Vs CNI Vs CSI in Kubernetes 👇 1. CRI (Container Runtime Interface): How kubelet talks to container runtimes 2. CNI (Container Network Interface): How pods get network connectivity 3. CSI (Container Storage Interface): How pods get persistent storage Here, the key pattern is, K8s defines the interface, vendors build the plugins. → 𝗝𝗼𝗶𝗻 𝗛𝗲𝗿𝗲 (𝟭𝟬𝟬% 𝗳𝗿𝗲𝗲): newsletter.devopscube.com/ We share deep dives on Kubernetes, DevOps,MLOps, Cloud and GitOps ♻️ PS: Repost and share it with the DevOps community. #Kubernetes #DevOps

Senior DevOps Engineer Interview Questions The panel focused heavily on Kubernetes, Helm, Jenkins, AWS, Terraform, Prometheus & Grafana — all scenario-based and practical. Sharing the questions here so others preparing for similar roles can benefit ➡️ 😬Kubernetes — Scenario-Based Questions - Your Pod is restarting frequently. How do you identify the root cause? - A Deployment is stuck in "progressing" state — how do you troubleshoot? - How do you debug a CrashLoopBackOff issue? - How do you check which Pods are consuming high memory or CPU? - Node is in NotReady state — steps to investigate? - Your application is not accessible through service — what will you check? - How do you handle failed daemonset pods? - Persistent Volume not attaching — what’s your troubleshooting approach? - How do you perform rolling updates and rollbacks safely? - How do you perform health checks for Pods and Nodes in live environments? 😬Helm — Practical Questions - What are values.yaml and how do you override them? - How do you manage multiple environment deployments using Helm? - How do you debug a failed Helm release? - What is the difference between Helm Chart, Release, and Repository? 😬Jenkins — CI/CD Questions - Why choose Declarative Pipeline over Scripted Pipeline? - How do you integrate SonarQube into a Jenkins pipeline? - How do you build → containerize → push → deploy using Jenkins? 😬AWS — Scenario Questions - Your EC2 instance is unreachable — how do you diagnose? - How do you implement Auto Scaling with proper health checks? - Difference between ALB and NLB and when to use which? - S3 cross-region replication setup steps? - How to troubleshoot high latency in API Gateway? - How do you reduce RDS cost without downtime? - What happens if Terraform state is deleted in S3? - How do you secure your VPC workloads at scale? 😬Terraform — Infra as Code Questions - How do you recover from a deleted Terraform state file? - How do you create 50 EC2 instances with different configurations (dynamic blocks)? - Share your screen and write a terraform code to create a VPC with all there components and create a RDS database into VPC. 😬Prometheus & Grafana — Monitoring Questions - How do you set up custom metrics for Kubernetes pods? - How do you troubleshoot missing data points in Grafana dashboards? - How do you create alerts for high CPU or memory usage? 😬Reflection: This interview round was entirely hands-on, scenario-focused, and tested how well you handle production-grade issues, automation thinking, and troubleshooting skills. If you're preparing for DevOps/SRE roles — start practicing real scenarios, not definitions
